Vorrichtung zum Bohren von Gestein. Patentiert im Deutschen Reiche vom 7. März 1924 ab. Device for drilling rock. Patented in the German Empire on March 7, 1924.
Das Bohren von Gestein, vermittels eines durch Druckwasser mit großer Geschwindigkeit über die Vortriebsstelle geführten Schleifmittels ist bekannt. Bei den bekannten Vorrichtungen wird das Schleifmittel in den Druckwasserstrahl erst nach seinem Austritt aus dem Bohrkopfstrahl eingeführt, so daß die Schleifmittelkörperc'hen an der Düsenmündung nur auf der ihnen zugekehrten Seite des Druckwasserstrahles auftreffen und nur dieser Teil gegen die Arbeitsstelle geschleudert wird. Da ein großer Teil des Schleifmittels den Druckwasserstrahl erst durchdringt, wenn es an der Bohrstelle angelangt ist, wird nicht das ganze im Druckmittelstrahl innewohnende Arbeitsvermögen ausgenutzt, indem die von der Oberfläche des Druckmittel-Strahles mitgenommenen Schleifmittelteile nicht zur vollständigen Wirkung gelangen.The drilling of rock, by means of one abrasive guided by pressurized water at high speed over the jacking point is known. In the known devices, the abrasive is in the Pressurized water jet introduced only after its exit from the drill head jet, so that the abrasive bodies at the nozzle mouth only on the side facing them of the pressurized water jet and only this part is thrown against the work site will. Since a large part of the abrasive only penetrates the pressurized water jet, when it has reached the drilling site, the whole is not in the pressure medium jet inherent work capacity exploited by the pressure medium jet from the surface The abrasive parts that have been taken along do not achieve their full effect.
Um diese Nachteüe zu beheben, wird nach ao der Erfindung vorgeschlagen, das Schleifmittel in das Innere des Druckwasserstrahles vor seinem Austritt aus den Bohrkopf düsen derart einzuführen, daß es schon an derTo remedy this night, ao proposed the invention, the abrasive in the interior of the pressurized water jet before it emerges from the drill head nozzle in such a way that it is already at the
